The Specification of Casting Steel Ball
Low Chrome Casting Steel Ball
Chrome Concentration is 1-3%, hardness ≥ HRC 45, impact value
≥1J/CM^2, this steel ball is called low chrome grinding balls,
which is made by smelting in intermediate frequency electric
furnace, metal mould or sand casting process. It applies to
metallurgic mines and slag industries where no high grinding
accuracy or wearability is required.

High Chrome Casting Steel Ball
High chrome casting grinding ball, chrome concentration is 10%-24%,
hardness ≥HRC58, impact value ≥3.5J/CM^2. High chrome casting
grinding ball is one of the wearable steel ball with better
performance-price-ratio, and its extensive usage has won itself a
high share in the market.
